To each their own. I carry 5 putters in my bag, and all of them have a different use.

I've become a big putter player recently, but my go to is actually a classic Roc. People might argue this is an approach disc, but for me it feels the best in the hand. I keep two of them, because of how fast they break in. One that is flippy and will go straight and finish anhyzer if hucked, where as the other is newer and used for tight straight drives/slightly longer putts with narrow paths

I have a couple wizards, one really flexy that is my go to putter on a windy day or for shots where theres a high chance of roll away. The other is much stiffer and is perfect for slow hyzer drives/spike hyzer approach shots. The stiffer one also makes for a good emergency roller if you really get into a nasty spot near the basket. These are also my go to anhyzer putters.

And just the other day i picked up an EZE Mercy by latitude 64 that feels great in the hand. Not to soft, but not stiff. Plastic is pretty grippy and it has been amazing as my driver putter. If i put everything into it, it goes nice and straight and finishes with a slow anhyzer fade, but if toned down just slightly it will run a very long straight shot.

So really there isn't one best putter, but go to a shop and feel out a few and then give um a try. Luckily putters are pretty cheap and you can get a couple for the price of one other disc, and worst comes to worse, just trade it away for a different putter with one of your buds.
